Thermal Control System for Japanese Experiment Module 891519

The baseline configuration of the Thermal Control System (TCS) of the Space Station (SS) Japanese Experiment Module (JEM) is defined as a result of the preliminary design study. The preliminary design study (phase-B and the extension study) was performed from 1985 to 1989 to define the functions and performances of the JEM TCS, and the functional/physical interfaces between the JEM TCS and the users (subsystem equipments and mission payloads). In addition, the functional/physical interfaces between the JEM TCS and the SS core TCS were studied at the same time.

The JEM system requirements are studied for Japan Preliminary Requirements Review (JPRR), and the phase-C and -D development. This paper gives an overview of the JEM TCS design and describes its baseline configuration, as well as some of the trade-off studies and analyses performed during the preliminary design phase [1]*.
